Ten-color 15-antibody flow cytometry panel for immunophenotyping of lymphocyte population

We have developed a lymphoproliferative disorder screening tube (LPD-ST) with the aim to provide comprehensive immunophenotyping of lymphocyte subsets with minimal need for additional testing. The LPD-ST consists of CD4/kappa FITC, CD8/lambda PE, CD3/CD14ECD, CD38PC5.5, CD20/CD56PC7, CD10APC, CD19APC-A700, CD5APC-A750, CD57/CD23PB and CD45KO. The LPD-ST was validated against previously used lymphocyte subset panels in Canada (n=60) and in Sweden (n=43) and against the OneFlow™ LST (n=60). The LPD-ST panel was then implemented in clinical practice using dried monoclonal antibody reagents (Duraclone®) on 649 patient samples in Sweden. In 204 of 649 samples (31%), a monotypic B-cell population was found. Of these cases, a final diagnosis could be rendered in 106 cases (52%), and in the remainder, additional B-cell immunophenotyping was performed. In 20 (3%) samples, an aberrant T-cell population was confirmed by additional testing. Of 425 samples diagnosed as normal/reactive lymphoid tissue, 50 (12%) required additional immunophenotyping, mostly due to an abnormal CD4/CD8 ratio. The LPD-ST tube significantly minimizes the need for additional testing, improves the turn-around time, and reduces the cost of LPD immunophenotyping. It is also suitable for investigating paucicellular samples such as cerebrospinal fluid or fine needle aspirates.
